To get a job in the game studios can’t be quite different for everyone but in the end is about your portfolio, if you portfolio is good then you get more attractive in the market.
Send your portfolio everywhere and write to studios. It might just stick somewhere.
Sometimes a studio don’t know they need a fx artist until one shows up, so just keep making assets and push your limits.
Be prepared that you might not be working in Unity nor Unreal, in many jobs they have their own engines and similar, having a positive attitude about this can go a long way.
Check out @Partikel’s thread here for what he usually looks into in portfolios What I/Studios look for in a reel
I also recommend that you attach your portfolio/reel or whatever into your online profiles (like this one, I can’t find you portfolio in your profile, I must look into the threads you write in) make it easy for recruiters to easily find your work everywhere.
To find indies: join indie game groups (tigsource, polycount, facebook indie game dev groups). Write to developers, send your work and make sure to post your work.
Remember to focus on what you are good at and keep pushing that.
